Subject: Splice status

Hi

I have been trying to test splice on kernel 2.6.35_4 (x86) from Samba (v3.4.7) but could not copy more than ~60MB to the Samba server share.

Strace shows that the splice got stuck in blocking mode on the splice call from socket to pipe.

Has anyone managed to get splice from socket to fd work for large files (up to 4G file size) ?
